An image capturing optical lens assembly includes, in order from anobject side to an image side, a first lens element, a second lenselement, a third lens element, a fourth lens element and a fifth lenselement. The image capturing optical lens assembly further includes animage sensor located on an image plane.

The first lens element with positive refractive power provides partialrefractive power for reducing the total track length of the imagecapturing optical lens assembly so as to maintain the compact sizethereof. The first lens element has a convex object-side surface, andcan have a convex image-side surface or a concave image-side surface.When the first lens element has a convex image-side surface, therefractive power of the first lens element can be enhanced for furtherreducing the total track length of the image capturing optical lensassembly. When the first lens element has a concave image-side surface,the astigmatism of the image capturing optical lens assembly can becorrected, so that the image quality of the image capturing optical lensassembly can be improved.

The second lens element with negative refractive power has a concaveobject-side surface and a convex image-side surface. Therefore, theaberration generated from the first lens element with positiverefractive power can be corrected.

The third lens element can have positive refractive power or negativerefractive power. When the third lens element has positive refractivepower, the sensitivity of the image capturing optical lens assembly canbe adjusted. When the third lens element has negative refractive power,the high order aberration of the image capturing optical lens assemblycorresponding to the second lens element can be reduced. The third lenselement has a concave object-side surface and a convex image-sidesurface, so that the aberration of the image capturing optical lensassembly can be corrected. Moreover, the object-side surface and theimage-side surface of the third lens element are aspheric.

The fourth lens element with positive refractive power can reduce thesensitivity of the image capturing optical lens assembly in accordancewith the first lens element. The fourth lens element has a concaveobject-side surface and a convex image-side surface, so that theastigmatism of the image capturing optical lens assembly can becorrected. The fourth lens element is made of plastic material, and theobject-side surface and the image-side surface thereof are aspheric.

The fifth lens element can have positive refractive power or negativerefractive power. When the fifth lens element has positive refractivepower, the total track length of the image capturing optical lensassembly can be further reduced. When the fifth lens element hasnegative refractive power with a convex object-side surface and aconcave image-side surface, the principal point of the image capturingoptical lens assembly can be positioned away from the image plane, andthe total track length of the image capturing optical lens assembly canbe reduced so as to maintain the compact size thereof. The fifth lenselement is made of plastic material, and the object-side surface and theimage-side surface thereof are aspheric. Moreover, the fifth lenselement has at least one inflection point formed on at least one surfacethereof, so that the incident angle of the off-axis field on the imagesensor can be effectively minimized and the aberration can be correctedas well.

When a focal length of the image capturing optical lens assembly is f,and a focal length of the fifth lens element is f5, the followingrelationship is satisfied: −1.75<f/f5<0.50. Therefore, the refractivepower of the fifth lens element can correct the aberration generatedfrom the fourth lens element. Preferably, f and f5 can satisfy thefollowing relationship: −1.3<f/f5<0.

When the focal length of the image capturing optical lens assembly is f,and a focal length of the third lens element is f3, the followingrelationship is satisfied: −1.3<f/f3<0.5. Therefore, the refractivepower of the third lens element is proper for correcting the aberrationof the image capturing optical lens assembly. Preferably, f and f3 cansatisfy the following relationship: −0.5<f/f3<0.5. Moreover, f and f3can satisfy the following relationship: −0.5<f/f3<0.

When a curvature radius of the object-side surface of the fifth lenselement is R9, and a curvature radius of the image-side surface of thefifth lens element is R10, the following relationship is satisfied:|R10/R9|<1.0. Therefore, the astigmatism and the distortion of the imagecapturing optical lens assembly can be corrected by the curvature of thefifth lens element, and the incident angle on the image sensor can bereduced for enhancing the sensitivity of the image capturing opticallens assembly, and improving the photographic performance of the imagesensor.

When an Abbe number of the first lens element is V1, and an Abbe numberof the second lens element is V2, the following relationship issatisfied: 31<V1−V2<42. Therefore, the chromatic aberration of the imagecapturing optical lens assembly can be corrected.

When a curvature radius of the object-side surface of the second lenselement is R3, and a curvature radius of the image-side surface of thesecond lens element is R4, the following relationship is satisfied:−1.8<(R3+R4)/(R3−R4)<−1.0. The curvature of the surfaces of the secondlens element can corrected the aberration generated from the first lenselement. Preferably, R3 and R4 can satisfy the following relationship:−1.5<(R3+R4)/(R3−R4)<−1.0.

When a curvature radius of the object-side surface of the first lenselement is R1, and a curvature radius of the image-side surface of thefirst lens element is R2, the following relationship is satisfied:|R1/R2|<0.3. Therefore, the spherical aberration of the image capturingoptical lens assembly can be corrected, and the total track lengththereof can be further reduced.

When an axial distance between the second lens element and the thirdlens element is T23, and an axial distance between the fourth lenselement and the fifth lens element is T45, the following relationship issatisfied: 0<T45/T23<0.5. Therefore, the fabrication of the lenselements can be easier due to the distance between of the lens elements.

When a curvature radius of the object-side surface of the third lenselement is R5, and a curvature radius of the image-side surface of thethird lens element is R6, and the following relationship is satisfied:−0.5<(R5−R6)/(R5+R6)<0.5. Therefore, the refractive power and thecapability for correcting the aberration of the third lens element areproper by adjusting the curvature of the surfaces of the third lenselement.

When an axial distance between the object-side surface of the first lenselement and the image plane is TTL, a maximum image height of the imagecapturing optical lens assembly is ImgH, the following relationship issatisfied: TTL/ImgH<2.3. Therefore, the total track length of the imagecapturing optical lens assembly can be reduced so as to maintain thecompact size of the image capturing optical lens assembly for portableelectronic products.

When the focal length of the image capturing optical lens assembly is f,and a focal length of the fourth lens element is f4, the followingrelationship is satisfied: 0<f/f4<2.0. The refractive power of thefourth lens element is proper for reducing the sensitivity of the imagecapturing optical lens assembly corresponding to the refractive power ofthe first lens element.

According to the image capturing optical lens assembly of the presentdisclosure, the lens elements thereof can be made of glass or plasticmaterial. When the lens elements are made of glass material, thedistribution of the refractive power of the image capturing optical lensassembly may be more flexible for design. When the lens elements aremade of plastic material, the cost of manufacture can be effectivelyreduced. Furthermore, the surface of each lens element can be aspheric,so that it is easier to make the surface into non-spherical shapes. As aresult, more controllable variables are obtained, and the aberration isreduced, as well as the number of required lens elements can be reducedwhile constructing an optical system. Therefore, the total track lengthof the image capturing optical lens assembly can also be reduced.

According to the image capturing optical lens assembly of the presentdisclosure, when the lens element has a convex surface, it indicatesthat the paraxial region of the surface is convex; and when the lenselement has a concave surface, it indicates that the paraxial region ofthe surface is concave.

According to the image capturing optical lens assembly of the presentdisclosure, the image capturing optical lens assembly can include atleast one stop, such as an aperture stop, glare stop, field stop, etc.Said glare stop or said field stop is allocated for reducing stray lightwhile retaining high image quality. Furthermore, when the stop is anaperture stop, the position of the aperture stop within an opticalsystem can be arbitrarily placed in front of the entire optical system,within the optical system, or in front of the image plane in accordancewith the preference of the optical designer, in order to achieve thedesirable optical features or higher image quality produced from theoptical system.
